+* Texas Instruments OMAP4+ McPDM
+
+Required properties:
+- compatible: "ti,omap4-mcpdm"
+- reg: Register location and size as an array:
+       <MPU access base address, size>,
+       <L3 interconnect address, size>;
+- interrupts: Interrupt number for McPDM
+- interrupt-parent: The parent interrupt controller
+- ti,hwmods: Name of the hwmod associated to the McPDM
+
+Example:
+
+mcpdm: mcpdm@40132000 {
+        compatible = "ti,omap4-mcpdm";
+        reg = <0x40132000 0x7f>, /* MPU private access */
+              <0x49032000 0x7f>; /* L3 Interconnect */
+        interrupts = <0 112 0x4>;
+        interrupt-parent = <&gic>;
+        ti,hwmods = "mcpdm";
+};
